Blood Testing for Better Performance - Learning from Hakone and Pro Baseball

Every year my new year starts with the Hakone Ekiden. Recently the performances at Hakone have improved at a surprising rate, in particular the uphill Fifth Stage, which despite going up the side of a mountain has seen new records virtually every year lately. Five years ago at Juntendo University I tested the blood of Masato Imai, known as "The God of the Mountain." In cooperation with the university medical department Juntendo checks its runners' blood almost every day beginning a week before Hakone. I myself took blood every month throughout the year and reported the runners' conditions to the team. Based on that data the coach made plans for training and team strategy. This experience gained as a sports doctor also applies in my work with general patients.

Among the data derived from a blood checkup, the G.O.T. and G.P.T., readings show not only the functioning of the liver but also the condition of the body's musculature. C.P.K. shows the degree of muscle fatigue, and L.D.H. shows the overall fatigue level of the entire body. If those two readings are high you can predict some inflammation of the muscle or even the likelihood of a strain or pull. In addition, if the number of white blood cells exceeds 10000 per microliter there is a high possibility of an impending muscle pull within the next week, indicating the need for a reduction in training. Those numerical values are very important for both amateur golfers and amateur marathon runners.

In ekidens the most important factor is the level of blood-borne serum iron and ferritin. They create the basic endurance capacity and help with coping with any kind of weather conditions. In a very hot summer training camp when runners are doing high mileage they crush the red blood cells flowing through their feet, leading to sports anemia. Including October's Hakone Ekiden Yosenkai qualifying race, the most important season of the year begins in the autumn. Naturally, it's important in this season to take in iron from liver, red meat and fish, but in order to improve the absorption factor it's also essential to take a vitamin B complex and vitamin C along with such foods.

An important factor in starting member selection for a key race such as Hakone is M.C.V., the average red blood cell volume. This is indicative of the athlete's stress level. In high-risk sports such as martial arts athletes usually show a higher count on this reading. Professional baseball player Kazuhiro Kiyohara used to show higher counts before the Japan Series, likely due to nervousness. On the other hand, pitchers Masumi Kuwata and Daisuke Matsuzaka maintained ideal numerical values and had brilliant concentration abilities in important games. In his daily bloodwork the M.C.V. of Hakone's God of the Mountain also improved day by day at the end of the year leading into the race. That showed how good he is at dealing with stress and being able to concentrate under pressure.

Calcium is important for agility because it encourages synaptic communication between nerve cells and muscles and helps with the precision of the intended movement. Eat small fish and supplements daily and take vitamin C along with it. I recommend taking iron, vitamin B complex, vitamin C, vitamin E and calcium every day, and you will be ready to face whatever your personal mountain is.

Nagoya Asian Games Test Event Canceled After Insulation Falls From Venue Ceiling

A section of insulation material fell from the ceiling of Nagoya Kinjo Futo Arena, the official venue for squash competition at September's Nagoya Asian Games. There were no injuries, but the city suspended use of the arena until its safety could be guaranteed, resulting in the cancelation of the Asian Games squash test event which was scheduled to have begun on May 14. It is not yet clear whether the arena will be usable for the Asian Games as planned. According to city officials, arena staff found that the insulation material had fallen onto a work walkway 13 m above the ground on the night of May 11. The fallen material was 3.6 m long, 50 cm wide and 2.5 km thick, and was found to be waterlogged. The cause of the accident is unknown, but it is possible that it was caused by rainwater leaking in from the roof. The same insulation material is installed across the entire ceiling, and the city plans to check for the extent of the possible flooding. Asked whether the arena will be re...

Hakone Ekiden Qualifying Race Entry Roster Sizes Increased from 14 to 16

Hakone Ekiden organizers KGRR have announced details for the qualifying half marathon for next year's 103rd Hakone Ekiden. The Yosenkai qualifying race will be held Oct. 17 in Tachikawa, Tokyo. The combined times of the 10 fastest finishers from each participating team will be used for team scoring, with the 10 fastest teams going on the the main event next January and top-placing individuals from teams that do not qualify being names to the Kanto Region Student Alliance select team. One change from previous years is that the number of runners each school can enter has been increased from 14 to 16. Teams will still only be allowed to have from 10 to 12 athletes on the starting line, but the move gives coaches greater flexibility in making the final decision on their starting rosters. No changes have been made to the qualifying times of 34:00 for 10000 m or 1:13:00 for the half marathon, and the new earlier starting time of 8:30 a.m. introduced last year in an effort to mitigate ...
